Anyone tried a modelgun .38 or .357 cartridge with 5mm or 7mm caps in one of the spring powered airsoft revolvers? Wondered about trying that, since it seems like there's a plastic 'firing pin' that pushes the airsoft bb out... and might be up to the task of setting off one of those caps. Don't have any modelgun revolver casings to test it with, though. If it works, it'd certainly be a cheap way to get more options for revolvers, and it'd be nice to have that smoke and bang for prop use.
